Wow, that was quick! And simple! Yes, of course that fixed it.
However, one good answer deserves another question:
I now have empty logs being created, which is a step in the right
direction. But can I eliminate the "unknown" logs completely? Right now
every time my app fires up it creates an "unknown" directory and the
empty timestamped log. Since this is a long running batch application, I
will quickly end up with a bunch of these and it would be great if I
could prevent them completely.
Possible?
Thanks very much for your quick response.

Hi,
This has been written about before in this list, and I thought it would
be easy, but I'm getting nowhere. Can anyone suggest what I'm doing
wrong? I can confirm that my filter code is running (I see the print
statements) but no matter what I return, I still end up with a log like
"unknown/batchqc-<timestamp>" containing plenty of log data.
I would like to eliminate these logs completely, and write logs using
this sifter only when articlePath is set.
The status listener is reporting:
12:03:35,652 |-ERROR in ch.qos.logback.core.joran.spi.Interpreter@25:37
- no applicable action for [OnMismatch], current pattern is
[[configuration][appender][filter][evaluator][OnMismatch]]

What am I missing?
